Peutz-Jeghers syndrome (PJS) is a disorder passed down through families (inherited) in which the person develops intestinal polyps. A person with PJS has a high risk developing certain cancers.
It is unknown how many people are affected by PJS. However, the National Institutes of Health estimates that it affects about 1 in 25,000 to 300,000 births.
There are two types of PJS:
The polyps develop mainly in the small intestine, but also in the colon. A colonoscopy will show colon polyps. The small intestine is evaluated with either a barium x-ray (small bowel series) or a small camera that is swallowed and then take multiple pictures as it travels through the small bowel (capsule endoscopy).
Additional exams may show:
Laboratory tests may include:
Surgery may be needed to remove polyps that cause long-term problems. Iron supplements help counteract blood loss.
Persons with this condition should be monitored by a health care provider and be checked periodically for cancerous polyp changes.
There may be a significant risk of these polyps becoming cancerous. Some studies link PJS and cancers of the gastrointestinal tract, lung, breast, uterus, and ovaries.
Call for an appointment with your health care provider if you or your baby have symptoms of this condition. Severe abdominal pain may be a sign of an emergency condition such as intussusception.
Genetic counseling is recommended if you are planning to have children and have a family history of this condition.
